Replacement I/O Board for HP X360 M6004DX

This new SMUGDESK board replaces the original part numbers 856792001, 448.07N02.0021 and 448.07N02.0011. It combines a USBA port, audio jack and power button circuit into a single module. The unit is built to match the factory connector layout exactly. It serves as a direct repair part for the specified notebook model.

For owners fixing power, USB or audio faults

The board suits anyone whose HP X360 M6004DX suffers from a broken power switch, damaged USBA port or faulty audio socket. It is not for users of other HP models or different laptop brands. Buyers needing a standalone USBA hub, external audio adapter or separate power button should look elsewhere. This part addresses only the integrated I/O board failure on the named device.

Plugandplay fit with careful disassembly

Installation follows a plugandplay design that requires no modification to the board or chassis. The main difficulty lies in opening the laptop case and routing the fragile ribbon cables without tearing them. Misaligned connectors or forced insertion can damage the new board or the motherboard header. Patience and a clean workspace are essential for a successful swap.

Questions about this item

Does my HP X360 M6004DX need the original motherboard connector for this 856792001 board to plug in?

Yes, the board uses the laptop's existing motherboard header; no extra cables or adapters are required beyond the original connector.

Will the USB-A port on this 448.07N02.0021 board still work if I keep my older USB 2.0 flash drives?

The port is backward compatible, so legacy USB 2.0 drives will function normally at their rated speed.

After fitting the 448.07N02.0011 board, how can I confirm the power button, USB-A port and audio jack are all working?

Press the power button to start the laptop, insert a USB device to verify enumeration, and plug in headphones to check audio output.
